invention has "for its principal objects. the 1 improved apparatus: (l)

provision of a; which will cut tl. glass positively and with a minimum amount of attention on lh i part of the attendants about the machine; which will center the glass sheets with respect to the cutting appc ratus to in :ro triuuninp; oil the some amount of glass on the two sides of the sheets; in which the movement 01 the cutting apparatus will be automatically stopped and such apparatus returned to sm ing position after each cut; and which 1:; simple in construction nd eliablo in operation.

a. portion oi the inspection shed are the rails 10, 10, upon which is mounted the truck 11, which carries the edge trimming or cutting devices. The rails 10, 10 are preferably of the L-scction, as indicated in Fig. l", and are supported by a series of links 12, 12, 12, etc, which links are pivoted. at their outer ends to the tracks b v' menus of the pivots 13 and at their inner ends are pivoted. to the longitudinull extending rails 141 by means of the pivots 15 (Fig. The rails 1 1 are in turn supporlcz'l by b 'ackcl's 1(3 hung upon the casings 17 s1irroundinothe leer openings 18.
